2 Claims. (01.150-52) This invention relates to shipping packages, andhas special reference to insulating devices for enclosing boxes orcartons containing the merchandise to be shipped or for directlyenclosing and protect the same.

tons; and the device consistsof heat insulating means for protecting themechandise confined thereby.

An object of the invention is to provide a flexible I and pliable memberhaving its edges attached together-and provided on its opposite endswith flaps adapted tobe folded in cooperative relationship to form apackage or enclosure for a carton, box, or other articles ormerchandise, and to insulate Another object of the invention is toprovide a device of the character mentioned having detachable means forfastening the flaps in proper cooperative relationship, said means beingeasily de- I tachable to permit all of the flaps to be extendedlongitudinally and thereby facilitate the folding of the device alongtwo diagonally opposite corners to superimpose one-half of the deviceupon the other in flat relationship.

Other objects will appear from the following description, referencebeing made to the annexed drawings, in which Fig. 1 is a plan view ofthe member used to form the package.

Fig. 2 is a plan View of the package collapsed or folded alongdiagonally opposite corners to superimpose one-half of the device uponthe other in flat relationship and thereby obtain one of the principalobjects of the invention.

Fig. 3 is a perspective view of the package hav: ing all of its endflaps unattached and extended.

Fig. 4 is a perspective view showing the flaps at one end folded andattached together and the fiaps at the other end unattached andextended.

Fig. 5 is a View similar to Fig. 4 showing the package inverted from theposition shown in Fig. 4 and containing a box or carton.

Fig. 6 is a perspective view of the completed package in which the flapsat opposite ends of the '1 package are attached in cooperativerelationship.

Fig. '7 is a vertical sectional view approximately on the line 7----''!of Fig. 6.

The device comprises two duplicate flexible and pliable wall members 1and 2 having at each end f1 three longitudinal slits 3, thereby formingat each end four end flaps 4, 5, 6 and 7.

These walls 1 and 2 are attached together along their marginal edges andat each side of the slits 3 by stitches 8 and the space between thewalls is filled with a layer 9 of kapok, which constitutes thehighlysatisfactory insulating material superior even to cotton or felt.

Longitudinal rows of stitches 10 extend from the inner ends of theslits-3 at one end of the device to the inner ends of the slits 3 at theopposite end, and longitudinal rows of stitches 11 extend from end toend of the device between the rows of stitches 10.

The-ends of this device are attached together by stitches 12, or otherfastening means, so as to form a tubular member that may be opened inapproximatelyrectangular form,the lines between the inner ends of therespective slits 3 constituting convenient fold lines for the corners ofthe device.

When in this form and when the flaps at opposite ends are unattached,the device may be folded easily along two diagonally opposite lines 10or along one of the lines 10 and along the line 12 so as to superimposeone-half of the device flatly upon the other, as should be clearlyunderstood by reference to Fig. 2 of the drawings.

When open in rectangular form, the flaps 7 and 6 at one end are foldedinwardly to position in which their ends are adjacent to each other andthen the flaps 4 and 5 are folded inwardly upon and against the flaps 6and 7 to position in which the ends of said fiaps 4 and 5 are adjacentto each other.

Buckles or fasteners 13 are attached to the flaps 4 by fasteners 14 andstraps 15 are attached to the flaps 5 at each end of the device. Whenthe flaps 4 and 5 are folded inwardly upon the flaps 6 and 7, the straps15 are engaged with the buckles 13 to fasten the flaps together in thecooperative relationship indicated and thereby hold the device in theform of a rectangular box or package open at one end and closed at theother.

A strap 16 is attached to each flap '7 and. a buckle or fastener 17 issecured by an attaching device 18 to the wall, of'which the flap 6 is anextension. When the flaps 6 and '7 are folded inwardly upon the flaps 4and 5, the strap 16 is passed through a loop 19 in connection with themiddle strap 15 and is then extended and en gagedwith the buckle orfastener 17 in the manner clearly shown in Fig. 4.

Then the package is inverted from the position shown in Fig. 4 to theposition shown in Fig. 5 in which the open end of the package is upward.Any box or carton 20, or other articles, may then be placed in thispackage, or other merchandise may be placed in the package without usinga carton or box to confinethe same. After the package is filled, theflaps 4 and 5 at the upper end of the package are folded inwardly toendwise abutting relationship upon or adjacent to the box or carton 20,or other merchandise confined in the package, and the straps 15, inconnection with the flap 5 are engaged with the buckles or fasteners 13attached to the flap 4. Then the flaps 6 and '7 are folded inwardly uponand against the flaps 4 and 5 and the wide and elongated strap 16 thatis in connection with the flap '7 is passed through the loop- 9 that isin connection with the strap 15 and said strap 16 is engaged with thebuckle or fastener 17, thereby completing the assembly and closing ofthe package.

This device is absorbent and may be saturated or not, as desired, inorder to condition the same for various insulating uses. After themerchandisc has been removed from this package, the flaps at theopposite ends may be disconnected from each other and the device foldedwith onehalf fiat upon the other half, as shown in Fig. 2, and thusgiven a form that occupies comparatively little space and largelyreducing shipping and transporation costs and charges.

It must now be clear that this invention is a device of a highlysimplified construction that possesses numerous advantages overinsulating packages or devices heretofore constructed for application tosimilar uses. One of the principal advantages is the very considerablereduction in shipping and transportation charges and costs in returningthe articles to the source of shipment for further use. The device maybe folded into small space with much greater convenience than otherdevices with which I am familiar. I do not restrict myself in anyunessential particulars, but

what I claim and desire to secure by Letters Patent is:

1. A device of the character described comprising walls of insulatingmaterial forming an open ended rectangular enclosure, flaps inconnection with the ends of each wall, there being four of said flaps ateach end of the enclosure and the two opposite flaps at each end beingfolded inwardly toward each other and the remaining two opposite flapsat each end being folded inwardly toward each other and superimposedupon said first two flaps, straps each having one end attached to one ofsaid walls at each end of the wall and extending across and covering theedges of said two last named flaps at each end, and means for attachingsaid straps to the opposite wall.

2. A device of the character described comprising walls of insulatingmaterial forming an open ended rectangular enclosure, flaps inconnection with the ends of each wall, there being four of said flaps ateach end of the enclosure and the two opposite flaps at each end beingfolded inwardly toward each other and the remaining two opposite flapsat each end being folded inwardly toward each other and superimposedupon said first two flaps, straps each having one end attached to one ofsaid walls at each end of the wall and extending across and covering theedges of said two last named flaps at each end, means for attaching saidstraps to the opposite wall, and means connecting said two last namedflaps at each end and engaging said straps.
